Symptom Checker

Symptoms A-Z

Many health enquiries can be answered online with no need to telephone NHS Direct.

NHS Direct’s health and symptom checkers let you assess your symptoms online and receive personalised clinical advice on the best course of action, for example to see your GP, go to A&E or treat yourself at home.

Over the coming weeks, the range of symptom checkers will be expanded to include common ailments such as back pain, headache and rashes.

Check other symptoms

The initial assessment is NHS Direct’s starting point if you’re not sure what’s wrong with you. Use this checker if you have:

  • symptoms that are concerning you
  • a dental health issue

If you have an enquiry about named conditions - such as diabetes, high blood pressure, and so on - treatments, NHS services, or medicines, use the NHS Direct online enquiry service
